MEASURING AND FILLING- MACHINE.

Application led August 9, 1922. Serial No. 580,608.

a machine whereby small bags may bel rapidly filled with measured` quantities of tea or the like.

The object of the present invention is to generally improve and simplify machines of the character described; to provide a rotary measuring head connected with a hopper or other source of supply on one side and a' discharge or bag receiving spout on the other side; and further to provide a continuous driving member and means cooperatingy therewith whereby a one-half revolution will be intermittently transmitted to the measuring head once during each revolutionv of the contlnuous drlving member, sald cooperating means being manually actuated so that the rotarymeasuring head will only be rotated when bagskare placed on the spout. Other objects will hereinafter appear.

One form which my invention .may assume is exemplified in thefollowingy description and illustrated in the accompanying drawings, in which; l, y i

The machine forming the subject matter of the present application embodies a hopper A, a measuring mechanism'B, a driving mechanism generally indicated atY C, a discharge or fillingspout D, anda stand E of suitable construction whereby the machine as a whole is supported. vThe stand proper consists of a base section 2, a tubular upright. 3, and a fitting 4c, in which is secured v a' sleeve member 5, forming a part of the cylinder 6 in which is turnably mounted a measuring head 7 The cylinder 6` has an inlet opening 8 formed in its'upper end and a discharge opening 9 formed in its lower end. One side of the cylinder ispopenk and themeasuringl head is insertedor removed through this opening, the measuring head being secured in position when insertedby means of ahead member 10, details` of which are shown in Figs. 3, 6 and 7 this head being in turn secured by toits or any other suitable means 'as illustrated i y The head member 10 serves .two functions, first that of aretainer for securing the measuring head against endwise Vmovement when in position within the cylinder, and @secondly that of a'bearing for thek driving mechanism generally {indicatedat C,.thatis, a shaft 11 is here shown as forming an integral part ofthe measuring head. This shaft extends through a .bearing formed in the head 10l and it Vcarries a driving arm-12,

- which is keyedl or pinned thereto as indicated at 13. The outer, end of the shaft is reducedin diameter and carries a worm gear 14,which is driven by means of a .wormpin- 'ion lysec'ured von theshaft 16 of an electric motor 17,'saidmember being also supported by the vstand generally indicated at E.

driving latch18, see. Figs. 1,- 3,1 (10 and 11. Y

" This latch is indicatedat 18 and Ais secured the bolt' and latchmay be manually retracted and held in retracted position by means yh'asreceived its charge, it must'jbe removed 'manually retracted.

As previously stated shaft 11 is provided with a driving arm 12. This arm is perhaps best illustrated in Figs.` 3 and 4. The latch 18 when projected engages one end of the driving arm 124 and thereby forms a driving connection and in this manner rotates the driving arm together with the yshaft 11 and vthe measuring head.. The

driving connection is however, broken when a one-,half revolution is imparted by an automatic releasing latch indicated at 24, see Figs. 12 and 13.` This latch is V secured by means ofa bracket 25 to one side of the head member 10, and is so positioned that it will 'engage the end of the latch 18 and depress the same to such an extent that it will release the Vdriving arm 12. The latch 18 however assumes normal position the moment latch 24 ispassed and it is therefore in a position to engage the opposite end of the arm 12 when another one-half revolu tion has been completed. In other words with gear 14 rotating continuously, and due to the position ofthe latches shown at 18 fand 24, a one-half revolution will be imparted to shaft 11 andv the measuring head once .during each revolution 'of the gear.

This intermittent rotation of the measur-v ing head is necessary as the measuring head Visprovided with two receiving or measuring pockets as indicated atA 26l and 27. These pockets alternately align with the hopper A and the discharge spout D. When one of the pockets in the measuring head aligns with the hopper, filling thereof will take place. and when the headhas rotated a 'one-half revolution, the pocket will align with the spout and will assume a vertical ,posit/ion, thereby permitting they contents to discharge by, gravity. The next pocket will .thenalign with thelhopper andV as 'suchvwill 1fill automatically, and this will discharge during the next one-half revolution. Y

" In actual operation it is found that an operatoris not, always able to keep up with 'the'machina4 that is the operator takes a` bag fand places the mouth of the 'bag over 'the spout. When the bag has'been filled or and afnew'bag placed( in n, its" position. A

"skilled op'erator'cankeep up vv'with themachine, but even sofit'is necessary to stop the intermittent rotation of the measuring head "erly adjusting thevbottom sections.

fromtime to time as the supply of bags may run out or the operator may be interrupted or may have to stop temporarily for other reasons. A second releasing latch is therefore employed. This latch is shown in detail in Figs. 8 and 9 and is manually operated as follows:

Slidably mounted on the discharge spout D is an annular combined sleeve and collar 40, see Figs. 3 and4, and secured to one side of the head member 10, asat 41, is a bracket 42, in which is .slidably mounted a releasing latch v43. Disposed in alignment with the releasing latch is a pair of links 44 and 45. These links are centrally connected te a rod 46, which in turn is connected with the collar 40. The link 44 is` pivotally "connected to the housing, in which latch 43 is held, while link 45 is pivotally attachedto the latch. This link connection permits retraction or projection of the latch 43,'that is when the operator gras'psl a bag and-'places the Vmouth thereof over the spout D, the operator will at the same time lift the collar 40 in an upward direction. This movement is transmitted through rod 46 to lift the links to the dotted line position indicated at 47. The latch 43 is in this manner' retracted and as such will not interfere with latch 18. Latch 18 therefore will engage the driving arm 12 and will imparta onehalf revolution thereto. but if 'latch 43 stands in av projected position, it'will engage latch 18 and depress the same at the'time that it should engage the end of the driving arm 12, and it will retain the latch 18 in depressed position until arm 12 is passed. Hence. ifgear 14 is turning and latch4 43 is projected, n'o movement vwill be transmitted to the driving arm and the measuringhead. but if a bag is placed on the spout and the collar 40`is lifted, the driving'engagement will be made and a one-halfrevolution Vwill be imparted to the measuring head.. The

intermittent movement of the head is therefore under control of the operator and the movement is only transmittedwheny a-bag is placed on thel spout asv it otherwise remains stationary due to the action of, the latches 24 and 43.

By referring to Fig. 3. it willv be noted that the pockets 26 and 27 formed vin thf measuring head areprovided with false bottom sections and that these sectionsHa-re connected by threaded extensions, one screwing into the other. These false bottom sections are provided for the purpose of increasing or decreasingthe capacity of thepockets, or in other words for increasing ordcreasling the quantity of tea or otherllmaterial vdelivered to the bags.

v Practically :any quantity desired may be obtained by prop- For the purpose of insuringlaligrirnent of the pockets with the hopper 'and"`spout, re-

spectively a detent 50 is employed. This detent is carried by the driving arm 12 and is illustra-ted in detail in Fig. 5. The detent engages a notch 51 in the face of the head i() when proper alignment is obtained and as such positions the measuring head at the end of each one-half revolution.

As previously stated the machine here illustrated is particularly adapted for measuring tea and like materials. The tea is placed in the hopper A and is fed by gravity through the opening 8 into the pockets 26 and 27 when they register. Actual experience has however shown that the tea may clog and for this reason an agitating arm 60 has been employed. This arm is ormed on the lower end of a shaft 6l, which is journaled in the cover 62 of the hopper. A pulley is secured on the upper end of the shaft and is rotated by means of a belt 63, which is driven from a pulley 64 secured on a shaft 65 forming a part of the measuring head and rotating in unison therewith, this shaft being clearly illustrated in Fig. 3. The agitatingarm 60 is in reality driven by the measuring head and as such will be intermittently rotated in unison therewith, and will for this reason agitata the tea when the head is rotating and thereby stirring it up S0 that it may freely fall by gravity into the measuring pockets whenthey align.

While I have stated that the machine is employed for the purpose of measuring tea, it is obvious that it may be employed for any other purpose desired. I similarly wish it understood that while certain features of the present invention are more 0r less specifically illustrated, various changes in form and proportion may be resorted to within the scope of the appended claims. Also, that the materials and finish of the several parts employed may be such as the experience and judgment of the manufacturer may dicate or various uses may demand.

Having thus described my invention, what l claim and desire to secure by Letters Patent is- In a machine of the character described the combination with the measuring head, the cylinder enclosing the same and the discharge spout carried by said cylinder, of a shaft secured to the measuring head and extending through one side of the'cylinder, a driving arm secured to said shaft, a gear turnably mounted on said shaft, means for continuously rotating the gear, a driving latch carried by the gear and adapted to engage the driving arm, a stationary latch engageable with the `driving latch to automatically disengage the driving latch and the driving arm when ya one-half revolution has been imparted thereto, a second latch engageable with the driving latch to pre-vent engagement of the driving latch and the driving arm, a collar slidably mounted on the discharge spout, and means actuated by movement 0I the collar for retracting or projecting the last named releasing latch.
